*For patients who did not undergo lymph node dissection, the Mayo criteria were used intra-operatively to decide if lymphadenectomy should be performed. (For a description of the Mayo criteria see Mariani et al, Low-risk corpus cancer: is lymphadenectomy or radiotherapy necessary? Am J Obstet Gynecol 2000;182:1506–19.22)
BMI, body mass index; LN, lymph node.
